LiChrosorb® RP-8 LiChroCART®

Inner Diameter (I.D.) 4 mm
Length: 250 mm
Package Contents: 1 Column

LiChrosorb® is one of the most successful and reliable packing materials, used in HPLC for more than 25 years and 
documented in the literature in the form of several thousand applications. The totally porous irregular particles are 
finely graded in the 5, 7 and 10 μm range.

LiChrosorb® packing materials offer the compete program of non-polar derivatives (RP-8, RP-18, RP-select B) polar 
derivatives (Si 60 and Si 100). In addition to the analytical cartridges and columns, such as LiChroCART® 250-4 or Hibar
® RT 250-4, Merck Millipore offers semi-preparative cartridges LiChroCART® 250-10 as well as Hibar® RT columns
250-10, packed on request with various LiChrosorb® packing materials.

With LiChroCART® cartridges the user works with re-usable endfittings which fit different cartridge lengths. 
Since these cartridge holders may remain in the system and the capillary connections do not need to be detached, 
the cartridges may be changed within the shortest possible time. Changing a separation cartridge from a length 
of 125 to 250 mm and back presents no problems. Furthermore, the adaptation of internal diameter (3 mm or 2 mm) 
to the analysis problem is possible within a few minutes. The endfittings are designed to allow the cartridges to be 
hand-sealed at normal working pressures of 150 to 200 bar without the need for any tools. Only at higher pressures 
may further tightening with a wrench become necessary.
